Mock sample for your project: TransitFeeds API

Before using this API, we recommend you read our Authorization Guide for more information on how to generate an access token.
Please also be aware that our test environment is based on a subset of the production, if you are not returning any results try with big cities/airports like LON (London) or NYC (New-York).

API for the Water Linked Underwater GPS. For more details: http://www.waterlinked.com
Recommended approach for connecting to a Underwater GPS via the API is:
If "GET /api/" times out, the Underwater GPS is not running (on this IP address)
If "GET /api/" responds with 200 OK check that the api version returrned (eg "v1") is supported by the client (eg: also supports "v1").
If the api version returned does not match what the client supports: give an error to the user and recommend upgrading. (Eg: response is "v2" while client only supports "v1")
If "GET /api/" responds with 301 Moved permanently. "GET /api/v1/version" to check if the kit has a version earlier than 1.5.
"GET /api/v1/version" will always respond with 200 OK on Underwater GPS earlier than 1.5 release.
Configuration API is is not considered stable and will potentially be changed

Weather Forecast and Historical Weather Observation Data via an convenient, restful API.

Our atmosphere protects us from a hostile space radiation environment comprising high energy particles of solar and intergalactic origin. Solar radiation is significant during unpredictable and short lived solar flares and coronal mass ejections (CMEs); however, galactic cosmic radiation (GCR) is omnipresent. The GCR intensity varies with latitude, longitude, and time due to effects of solar activity on the interplanetary magnetic field, as well as the Earth's magnetic field. Space radiation collides with gases in the atmosphere, leading to a complex shower of high energy radiation, the intensity and composition of which varies spatially and temporally. Excessive exposure to radiation can damage DNA and lead to long-term health effects such as an increased risk of cancer. Resulting radiation levels at commercial aircraft altitudes are greater than at sea level due. Aircrew are classified as radiation workers in some countries; however, planning to limit their exposure, and monitoring, is generally lacking. Both real-time measurements and predictive models of radiation in the atmosphere are important to mitigate the radiation risk crew.
We host a RESTful API to models of cosmic ray induced ionising radiation in the atmosphere. The PARMA or CARI7 endpoints can be used to calculate Effective Dose or Ambient Dose Equivalent at a point.
The Route Dose API calculates the same quantities along a great circle route between two airports using CARI7.

Space has a hostile radiation environment that increases the risk of cancers in humans and malfunctions in spacecraft electronics. The types of space radiation of primary concern are:
Galactic Cosmic Rays from outside our solar system generated by
supernovae and other phenomena;
Solar Energetic Particles produced by the Sun during intense and
sporadic bursts of activity; and
Trapped Radiation: energetic particles confined by Earth's magnetic
field, usually comprising an inner belt of mostly high energy protons
and an outer belt dominated by lower energy electrons and plasma.
Understanding the space radiation environment for a particular mission profile is becoming increasingly important. Commercial off-the-shelf electronic components that aren't resilient to space radiation are now prevalent. Longer duration missions to cislunar space, Mars, and beyond are placing astronauts at greater risk of radiation exposure.

On some of our resources, we filter the content displayed based on the Accept-Language header.
If the language is not defined or if we don't use the language defined in this header, we automatically use French as the default language.
EcoTa.co currently support two languages: English, French. ("en" and "fr")
Encoding
All requests and answers on EcoTa.co are in UTF-8.

The gravitational field of the earth is non-uniform. The geoid is the shape the
ocean surface would take if only gravity and the rotation of the Earth
were considered. The geoid is the surface that defines zero elevation.
The geoid height is the difference between an ideal reference ellipsoid and the geoid.
The gravity anomaly is the difference between the acceleration due to gravity on the Earth's surface and the value calculated assuming the reference ellipsoid.
The official Earth Gravitational Model EGM2008 was developed and released to the public by the National Geospatial-Intelligence Agency (NGA).
Our EGM2008 API provides on-demand access to the EGM2008 model, as implemented by the open-source GeographicLib Gravity library.

Welcome to the Daymet Single Pixel Extraction Tool API. You can use this API to download daily surface data within the Daymet database in a csv or json format for a single point. This API allows users to query a single geographic point by latitude and longitude in decimal degrees. A routine is executed that translates the (lon, lat) coordinates into projected Daymet (x,y) Lambert Conformal Coordinates. These coordinates are used to access the Daymet database of daily interpolated surface weather variables. Daily data from the nearest 1 km x 1 km Daymet grid cell are extracted from the database.
